I'm looking into trying some longer exposures during daylight, but with the equipment I have I'm limited to only a few seconds. Does anyone have any suggestions on equipment that can be used to extend an exposure out to say....20 or 30 seconds. I've used a CPL with GND filters, but it's just not enough....and yes...low ISO...high aperture...I'm asking about equipment..filters..anything...
Any suggestions or tips are appreciated. Thanks.
